考虑了大磁场对激子绝缘体的影响。由于激子绝缘体不表现出迈斯纳效应（根据 Jerome、Rice 和 Kohn 最近的一篇论文），Hartree-Fock 基态可以用朗道能级基函数来表示。讨论了磁场相关相图和磁导率。激子绝缘体尚未通过实验观察到，但可以在常压下的高磁场中观察到。
The effects of large magnetic fields on the excitonic insulator are considered. Since the excitonic insulator does not display a Meissner effect (according to a recent paper by Jerome, Rice, and Kohn), a Hartree-Fock ground state can be expressed in terms of Landau-level basis functions. A magnetic-field-dependent phase diagram and the magnetoconductivity are discussed. The excitonic insulator, not yet observed experimentally, may be observable in high magnetic fields at normal pressure.
